What do you know about the Carbon Cycle and Climate?

The level of carbon dioxide in our atmosphere is regulated through a system of sinks and sources. Can you think of any examples in our Earth’s system where carbon is absorbed or released?    Learn about this by taking the “Carbon” Quiz.  Throughout 2014, new quizes will be unveiled as part of a NASA cross-mission project called “Know Your Earth”.

Take the Carbon quiz online at: http://climate.nasa.gov/quizzes/carbon-quiz/.
